A powerful magnitude 7.8 earthquake struck offshore near Mindanao in the southern Philippines on June 8, triggering tsunami warnings in the Philippines and neighboring Indonesia, according to the U.S. Geological Survey. The quake occurred at about 7:37 a.m. local time at a depth of roughly 35 kilometers, raising immediate concern for coastal communities in the region.
Philippine authorities issued a tsunami alert and urged residents in coastal areas to move to higher ground. The U.S. tsunami warning system said waves in some parts of the Philippines could reach 1 to 3 meters above tide level. Indonesia also issued a tsunami warning for its northeastern coast as officials monitored the impact of the offshore quake.
Images released by local authorities in General Santos City showed damage after the shaking, including a convenience store and other buildings that appeared to have collapsed. The strong tremors were felt across parts of Mindanao, one of the Philippines’ largest southern islands, which lies in a seismically active zone along the Pacific Ring of Fire.
Local police in Alabel, Sarangani province, said there were no immediate reports of deaths or injuries, though some people reportedly fainted because of the intensity of the earthquake. The police chief described it as the strongest earthquake he had experienced, underscoring the severity of the shaking and the level of alarm among residents.
The quake prompted emergency monitoring across both countries as authorities assessed whether a tsunami had been generated and whether further evacuations would be needed. Coastal residents were warned to remain alert for additional official instructions, as tsunami risk can persist after a major undersea earthquake.
The event follows a pattern of destructive seismic activity in the Philippines, which sits on several fault lines and is frequently hit by earthquakes and volcanic events. Officials continued to watch for aftershocks and possible damage to infrastructure, homes, and public facilities in affected areas.
Emergency agencies in the Philippines and Indonesia were expected to continue issuing updates as new information became available.
